Common Garbage Sorting Technologies and Applications

Through sorting recovery, the municipal solid waste can be separated into these materials, such as paper, plastic, fabric and other light combustible substance; scrap iron, steel wire, cooper, aluminum and other metal materials; glass, non-metallic materials and other inorganic substance. The sorting technology and its comprehensive comparison and applications are shown as follow:

Sorting technology Sorting materials Pretreatment requirement Applications
Manual sorting Waste paper, steel, non-ferrous metals, wood, etc. No Commercial, industrial and household waste collection station seized crepe paper, high-quality paper, metal, wood, etc.
Screening Glass, aggregate No pretreatment or crushing or sorting Sort glass or access to different sizes of materials from the heavy components
Wind election Waste paper, crepe paper and other combustible materials No The separation of combustible materials in light components and metal, glass and other materials in heavy components


Heavy medium sorting Aluminum and other non-ferrous metals Crush, wind election Separate a variety of metals by adjusting the density of heavy medium
Flotation Inorganic useful components Crush, pulp Separation of small and useful components
Magnetic sorting Iron metal Crush, wind election Sorting for large-scale industrial waste and municipal solid waste
Electrostatic sorting Glass, fly ash, etc. Crushing, wind selection, screening Sorting of lead and glass wastes or sorting of coal from fly ash
Photoelectric sorting Glass Crush, wind election Sorting glass from opaque waste or sorting hard glass from stained glass

In order to economically and effectively recover the useful substance in waste, two or more sorting units are often combined into an organic sorting recovery process system. The useful substance that have been sorted out can be used for resource utilization, such as:

1. Waste plastic, tires, rubber, medical waste, oil sludge: can be recycled by waste pyrolysis plant to make oil, carbon black and other useful resources. Moreover, the plastic can be make plastic granules by plastic recycling machine; tires and plastic can be used to make rubber powder by rubber powder machine.

2. The fuel oil generated from pyrolysis equipment can be converted into diesel oil by oil distillation plant.

3. Rice husk, sewage sludge, wood, sawdust, coconut shell, palm shell, straw, bamboo and other biomass waste: making charcoal by biomass pyrolysis plant.

4. The charcoal produced by carbonation machine can be further processed into high-quality N220, N330 carbon by BMF carbon black processing plant for wider applications.
